Evaluation of wave loads on a new type of perforated caisson

Abstract

Determinación de las fuerzas y esfuerzos horizontales sobre un nuevo cajón denominado Apolonio.
A new type of perforated breakwater has been tested combining the advantages of cylindrical geometry with
stepped wave energy dissipation. Thus, the new type of caisson implies a significant reduction of maximum wave
forces, as well as loads transmitted to the foundation in comparison with conventional vertical breakwater and other
types of perforated caissons. Starting from a brief description of the model and test results, this paper describes the
development of a methodology for the estimation of maximum wave loads on this type of breakwater, in order
to become a generalisable tool for predesign purposes. Construction and installation constraints of this new type of
caisson are also assessed. These need to be taken into account in order to keep some advantages from the proposed
design, while noting the key factors from a practical point of view.
